“#Throwback to when we were on our holiday. I was getting ready in the bathroom and husband was in the kitchen,” Blanksby wrote in the caption on March 6. “The kids were quiet, especially Mr. Preschooler.

“You know the rules about when kids are quiet. I tiptoed to the lounge with my camera ready to catch anything they are doing. I was expecting my baby to be covered in Nutella or something but instead I saw this. My preschooler is telling his baby brother “Kuya (big brother) is here. Everything is OK.”

“The irony of life has hit my family so hard and everything doesn’t make sense anymore,” Blanksby posted on March 4. “It feels like only yesterday when I posted about giving birth to our Rainbow Baby Thomas and here I am writing about his imminent death.”

“Watching my two sons together is a dream come true,” Blanksby wrote. “Being a family of four has always been part of my day dreams. It’s now my reality and it’s trapped in this nightmare no family should be in.”

A GoFundMe page set up on behalf of the family. In less than a month, the page has raised more than $40,000.
